JOSEPH 0. LUTHY,'OF SAN ANTONIO, TEXAS.

BATTERY-TERMINAL.

Application filed Xulv 1. 1918.

. citizen of the United States, residing at San Antonio, in the countyl of Bexar, in the State of Texas, have invented certain new and useful Improvements in Battery-Ter minals; and I do hereby declare the following to be a full, clear, and exa`ct description as will enable others skilled in the art to which it appertains to make and use the same. y

ln electrical systems where storage batteries are used, it is oft times necessary to replace the batteries, either permanently or temporarily. For instance, in the lighting, starting and ignition systems of automobiles, periodically the batteries must be replaced. t is acommon practice to substi- .tute a battery in a llighting, starting and ignition system, for a battery which must be recharged or repaired. There is a. common type of battery wherein the terminals are tapered sockets, usually truste-conical in tapered sockets, similarly tapered conductor terminals are adapted to Vhen one battery is substituted for another it very often occurs that the tapered conductor terminals are either too too small for the socket terminals of the new battery, so that itis very difficult undervordinary conditions to properly attach the conductor terminals to the battery.

I have provided means whereby the socket terminals of the, batteries will be adapted to conductor terminals of various sizes.

In the drawing:

Figure l is aplan view of a battery' with a socket vterminal and bushing thereof vin section, and with the conductor terminal partly broken away, the bushing illustrated being that us'ed when the socket terminal ot the battery is too large to accommodate the tapered terminal ot' the conductor;

Fig. 2 is a. similar view illustrating the bushing used when the socket ltecminal is too small to accommodate the conductor terminal;

Fig. 3 is a perspective view of the bushing illustrated in Fig. 1, and

Fig. 4 isa perspective view illustrated in Fig. 2.

In Fig. l el the drawing the battery is. indicated generally by the reference character 1, and the battery terminal by the character 2. This terminal includes a socket menlber 3, which is provided with a trusteot the bushing Specification of Letters Patent.

conical opening -1 adapted to receive the tapered terminal 5 of the conductor 6. This terminal 5 is provided in its end with a threadedopening i', into which a screw 8 is adapted to extend. This screw 8 passes through a lock washer 9, and when in threaded engagement with the opening l se cures the conductor terminal 5 socket member 3. The embodiment of the invention illustrated in Fig. l includes a4 frusto-conical bushing 10, which is located within the frusto-conical opening Je ot the socket member 3. This bushing is preferably made of -a lead composition, which contains aconsiderable" percentage et anti-- mony, which renders the bushing relatively hard and, therefore, suitable for commercial purposes. `When the conductor terminal 5. is too small to be drawn tightly into the socket member 3 by the screw S, as illusthe bushing l0 is placed in the opening 4 ot the socket member 3 and the terminal 5 of Ythe conductor 6 in serted in the bushing. TheA tightening of the screw 8 draws the terminal 5 tightly ,into engagement with the bushing l0 an also draws the gagement with the wall of the opening 4, so

trated in Fig. 1,

that a perfect contact is made.

In the form of the invention illustrated in Fig. 2, wherein the parts corresponding to those illustrated in Fig. 1, the same reference characters primed, the bashinglO is of the type used when the terminal 5 of the conductor 6 is too large to tit into the opening 4c of the socket member 3. This bushing 10 is provided with an opening l1', through which the screw 8 passes, and is provided with a. tapered opening 12'., into which the terminal 5 of the conductor 6 extends.

in this Jform of the invention likewisey draws the terminal 5' into intimate contact with the inner wall of the bushing l0 and also draws the outer surfaces of the 'bushing into intimate contact with the wall ot the opening 4. in the socket member 3.

"With 'these two forms of the invention, the, socket may he'adapted to receive conductor terminals of various sizes, irrespec tive of whether or not the terminals are too large or too small to properly it in and contact with the socket members themselves.

This invention is particularly useful aty has been X icrienced in connectie(r the vawithin4 the.

bushing 10 tightly into enare indicated by The tightening of' rious sized conductor terminals to the various sized battery terminals of the tapered socket type. The invention is particularly simpleand readily adapts the sockets to the 1' various sized conductor terminals with 'the consumption of the minimum time and labor, and furthermore, the Contact produced between the conductor terminals and the battery terminals is effective and positive, and there is no likelihood of the Contact being `broken during the jars incident to the 'use'of a battery on a lighting, starting and battervof the tapered terminal type is used.

' 'What I claim is:

l. The combination with a battery termi- 4nal having a tapered socket and a tapered conductor terminal, of a bushing removably interposed between the battery and conductor lterminals, and 'means for drawing the conductor terminal tightly into-engagement with the bushing and the bushing tightly into en,g ;agement with the battery terminal.

/ 2. The combination with an electric terminal including a tapered socket member and a tapered screw passing through the bushing and engaged with the conductor terminal to bind the parts together.

3. The combination with a-battery termimal having a tapered socket which is adapted tolreQeive tapered conductor terminals of a buslhifiig removably mounted in the socket to vary the range of the same.

In testimony whereof I afiix my signature.
